Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and particularly relates to a pathological wax block treatment device. Background Art

[0002] Currently, the treatment of waste wax blocks in pathological laboratories mainly relies on incineration or landfill. During incineration, incomplete combustion of paraffin will release highly toxic gases such as dioxins, while landfill will cause long-term pollution of soil and groundwater due to the poor degradability of paraffin. In the prior art, paraffin recovery mostly uses manual sorting combined with simple distillation method, but the manual operation efficiency is low and the recovery rate is less than 60%. The residual biological tissue still has the risk of biological hazard due to incomplete inactivation. Some laboratories try to carry out step-by-step treatment, such as the combination of an independent melting device and a sterilization cabinet, but such devices are large in volume, high in energy consumption, and cannot adapt to the space limitations of small laboratories. In addition, the traditional process lacks effective purification means for the residual organic solvents (such as xylene) after wax block treatment, which is likely to cause secondary pollution.

[0003] With the rapid increase in the number of pathological samples, the prior art has been difficult to meet the comprehensive requirements of high efficiency, safety, and environmental protection. For example, although the fully automatic dehydration-impregnation wax device has improved the efficiency of wax block preparation, it does not integrate paraffin recovery and biological inactivation functions, resulting in subsequent treatment still relying on external devices, increasing the operation complexity and cost. Although intelligent sorting technology has been introduced in the field of medical waste treatment, its design goal is for general waste and cannot directly adapt to the special physical and chemical properties of pathological wax blocks. Summary of the Invention

[0004] The present invention aims to provide a pathological wax block treatment device to solve the technical problems such as environmental pollution, low treatment efficiency, and biological hazard risk existing in the traditional pathological wax block treatment method.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A pathological wax block treatment device includes a box body, a hot melting component, a filtering component, and a sterilization component. The hot melting component is connected to the inner top end of the box body, the filtering component is connected to the bottom end of the hot melting component. The filtering component includes a first filtering component and a second filtering component. The first filtering component is used to screen out macromolecular impurities, and the second filtering component is used to adsorb cell debris. The first filtering component is located directly above the second filtering component. The bottom end of the first filtering component is connected to the sterilization component, and the bottom end of the second filtering component is connected to a collection tank.

[0006] Furthermore, the hot-melt assembly includes a rotating rod, a spiral blade, and a motor. The inner top end of the box body is connected with a fixing plate, and leakage holes are provided on the fixing plate. The rotating column is connected to the top end of the fixing plate, and the rotating column upwardly penetrates through the top end of the box body and is connected with the output shaft of the motor. The motor is connected to the outer top end of the box body. The motor drives the rotating column and the spiral blade to rotate, which can stir and break the pathological wax block, accelerate the hot-melt process of the wax block, and improve the hot-melt efficiency. The design of the leakage holes on the fixing plate facilitates the smooth falling of the molten paraffin into the subsequent filtering assembly, ensuring the smooth progress of the treatment process.

[0007] Furthermore, the side wall of the box body on the fixing plate is made of stainless steel and is divided into three parts. A ceramic fiber heat insulation layer is connected between the stainless steel and the inner wall of the box body. The inner walls corresponding to the three parts are all connected with electromagnetic induction coils. The three parts are an inlet section, a middle section, and an outlet section. The corresponding heating temperature of the inlet section is 80 - 120 °C, the corresponding heating temperature of the middle section is 120 - 150 °C, and the corresponding heating temperature of the outlet section is 150 °C. The segmented gradient heating can achieve precise melting according to the characteristics of paraffin, improve the recovery rate of paraffin, and reduce the decomposition of paraffin during the heating process. The ceramic fiber heat insulation layer can effectively reduce heat dissipation, improve the thermal energy utilization rate, and reduce energy consumption. The electromagnetic induction temperature control technology makes the temperature control more precise, ensuring the stability of the wax block treatment process.

[0008] Furthermore, the first filtering assembly includes a vibration motor and a screen. The screen is inclined and arranged at the bottom end of the fixing plate. A chute is communicated with the inclined part of the screen. One side of the screen away from the chute is connected with the output shaft of the vibration motor. The vibration motor makes the screen vibrate, which can more effectively screen out macromolecular impurities and improve the filtering effect. The screen is inclined and communicated with the chute, which facilitates the macromolecular impurities screened out to enter the sterilization assembly along the chute, avoiding the accumulation of impurities and affecting the filtering efficiency, and at the same time realizing the effective connection between the filtering and sterilization links.

[0009] Furthermore, the second filtering assembly includes a central pipeline and a plurality of honeycomb-shaped porous ceramic tubes. The plurality of honeycomb-shaped porous ceramic tubes are horizontally arranged and located directly below the screen. The central pipeline is connected to the bottom ends of the plurality of honeycomb-shaped porous ceramic tubes. The bottom end of the central pipeline is communicated with the top end of the collection tank. The honeycomb-shaped porous ceramic tubes have a large specific surface area and can efficiently adsorb cell debris, further purifying the liquid paraffin. The central pipeline converges and transports the purified liquid paraffin to the collection tank, ensuring the smooth collection of the liquid paraffin and enabling the effectively storage of the filtered liquid paraffin.

[0010] Furthermore, a waste liquid collector is connected to the top end of the collection tank. The waste liquid collector is connected to a hose that penetrates the box body and is located outside the box. A water pump is connected to the outer wall of the box body, and the water pump is connected to the hose. The centralized pipeline is connected to a steel pipe, and the steel pipe penetrates the box body and is connected to a cleaning box and a high-pressure valve. The waste liquid collector, the hose connected thereto, and the water pump cooperate to collect and discharge the waste liquid generated during the treatment process, preventing pollution caused by waste liquid residue.

[0011] Furthermore, one side of the bottom end of the box body away from the collection tank is a cavity, and the cavity is divided into two parts. The sterilization component includes a high-temperature sterilization chamber and a UV chamber. The top cavity is the high-temperature sterilization chamber, and the bottom cavity is the UV chamber. The high-temperature sterilization chamber is connected to the chute. The inner wall of the high-temperature sterilization chamber is provided with an electric heating plate, and a pneumatic discharge valve is provided at the bottom end of the high-temperature sterilization chamber. Multiple UV lamps are connected to the inner top end of the UV chamber, a tray is provided at the bottom end of the UV chamber, and a movable door is provided on one side of the UV chamber. The electric heating plate in the high-temperature sterilization chamber can perform high-temperature sterilization treatment on the screened macromolecular impurities, killing the harmful microorganisms therein. The UV chamber further disinfects the items that have undergone high-temperature sterilization to ensure the safety and harmlessness of the treated substances. The upper and lower layer design of the high-temperature sterilization chamber and the UV chamber, combined with the linkage of the pneumatic discharge valve and the tray, realizes the continuous inactivation and safe discharge of solid waste, improves the treatment efficiency, and ensures the safety of the operators.

[0012] The working principle of the present invention: When the pathological wax block treatment device works, the pathological wax block is placed in the box body, and the hot melting component is started. The heat generated by it melts the wax block into a liquid state. The liquid wax falls due to gravity to the filtering component, screening out the macromolecular impurities and making them enter the sterilization component. The liquid wax continues to fall through the sieve mesh, and the second filtering component plays an adsorption role to adsorb and remove cell debris, allowing the purified liquid wax to flow into the collection tank for storage. The screened macromolecular impurities enter the sterilization component and are treated by high-temperature sterilization and other means to kill the harmful microorganisms that may exist therein, ensuring the safety and harmlessness of the treated substances. The entire process realizes the non-contact hot melting, filtering, sterilization, and collection of pathological wax blocks, achieving the efficient and environmentally friendly treatment of pathological wax blocks.

[0013] The beneficial effects of the present invention: 1. Through the three-stage gradient heating (80 - 150 °C) of the hot melting component combined with the electromagnetic induction temperature control technology, the precise melting and anti-decomposition of paraffin are realized, and the recovery rate is increased to more than 90%, while avoiding the dioxin pollution caused by traditional incineration. The filtering component adopts a series design of a vibrating sieve mesh and a honeycomb-shaped porous ceramic tube to stepwise remove macromolecular impurities and cell debris, significantly reducing the residual organic solvents. Combined with the double inactivation (high temperature + UV) of the sterilization component, the finally recovered wax meets the medical-grade cleanliness standard, reducing the landfill pollution risk from the source.

[0014] 2. The vertical layout of the hot melting, filtering, and sterilizing components inside the box forms a compact processing streamline, reducing the space occupation by 50%, and adapting to small laboratory scenarios. The combined use of electromagnetic induction coil zoning heating and ceramic fiber heat insulation layer increases the thermal energy utilization rate by 40%, and reduces the energy consumption by 30% compared with traditional split equipment. In addition, the direct connection design between the chute and the sterilization chamber avoids the risk of biological exposure during the intermediate transfer process.

[0015] 3. The horizontal arrangement structure of the honeycomb-shaped porous ceramic tubes in the second filtering component not only adsorbs cell debris, but also synchronously enriches organic solvents such as xylene through capillary action on the surface micropores. Combined with the periodic backflushing of the high-pressure valve in the cleaning box, it realizes self-cleaning of the filter material and recycling of the solvent, solving the industry problem of secondary pollution caused by solvent residues in traditional processes. In addition, the upper and lower layered design of the high-temperature sterilization chamber and the ultraviolet chamber, through the linkage of the pneumatic discharge valve and the tray, realizes continuous inactivation and safe discharge of solid waste, and the inactivation efficiency reaches 99.99%, far exceeding the industry average level (85%-90%) of single sterilization methods.

[0016] 4. The inclination angle of the vibration motor and the screen is adapted to separate impurities of different particle sizes. Combined with the automatic control of the water pump and the three-way valve, it realizes classified collection and cyclic treatment of waste liquid. The operator only needs to feed materials once to complete the whole process, reducing the labor cost. Brief Description of the Drawings

The central pipeline 9 is fixedly connected to the bottom ends of the eight honeycomb-shaped porous ceramic tubes 8. The bottom end of the central pipeline 9 is communicated with the top end of a collection tank 17 through a three-way valve 10. Another port of the three-way valve 10 is connected to a waste liquid collector 22. The waste liquid collector 22 is located at the top end of the collection tank 17.

[0024] The bottom end of the box body 1 is divided into two cavities. The left cavity is a collection cavity 18. A collection tank 17 is placed at the inner bottom of the collection cavity 18. The right cavity is divided into upper and lower parts. The sterilization component includes a high-temperature sterilization chamber 11 and an ultraviolet chamber 14.

One side of the ultraviolet chamber 14 is a movable door.

[0025] The specific implementation process is as follows: When the processing device is working, first put the pathological wax block into the box body 1. At this time, the hot-melt component starts to function. The motor 2 drives the rotating column 3 and the spiral blade 4 to rotate, and preliminarily stirs and breaks the wax block. At the same time, the electromagnetic induction coil on the inner wall of the box body 1 starts to heat up. The inlet section is heated to 80 - 120 °C, the middle section is heated to 120 - 150 °C, and the outlet section is heated to 150 °C. In the gradually heating environment, the wax block is fully melted into liquid paraffin.

[0026] The melted liquid paraffin will fall onto the filtering component below. The vibrating motor 23 in the first filtering component vibrates the sieve mesh 6 to screen out the macromolecular impurities. These impurities will enter the high-temperature sterilization chamber 11 of the sterilization component along the chute 7 at the inclined part of the sieve mesh 6. And the preliminarily filtered liquid paraffin continues to flow downward to reach the second filtering component. The six honeycomb-shaped porous ceramic tubes will adsorb the cell debris in it to further purify the liquid paraffin. The purified liquid paraffin flows into the collection tank 17 through the centralized pipeline 9. After the filtration, the large-particle impurities remain on the filter mesh. At this time, start the vibrating motor 23. The vibrating motor 23 sends the large-particle impurities to the chute 7. The large-particle impurities enter the high-temperature sterilization chamber 11 through the chute 7. After being sterilized at a high temperature by the electric heating plate 12, they are discharged through the pneumatic discharge valve 15 to reach the ultraviolet chamber 14. The ultraviolet lamp 13 can further disinfect the items that have been sterilized at a high temperature. The items placed on the tray 16 can be taken out from the movable door after disinfection. When the honeycomb-shaped porous ceramic tube is blocked, the pressure inside the honeycomb-shaped porous ceramic tube changes. At this time, the high-pressure valve drives the cleaning box 21 to spray cleaning water reversely into the centralized pipeline 9. At this time, the valve connecting the centralized pipeline 9 to the collection tank 17 is closed, and the centralized pipeline 9 is connected to the waste liquid collector 22. The cleaning water with impurities flows down and is collected in the waste liquid collector 22 through the centralized pipeline 9. When the waste liquid reaches a certain level, under the action of the water pump 20, the waste liquid can be discharged through the hose 19.
